SPECIFICATION forming part of Letters Patent No. 282,040, dated July 31,1883, A

To all whom it may concern Be it known that I, RICHARD W. BENEDICT, ofPerry, in the county of Wyoming and State of New York, have inventedcertain new and useful Improvements in Harvesters, of which thefollowing is a specification.

My invention relates to improvements applicable to machines of the typeespecially designed'for cutting grass, and usually termed two-wheeledfront-cut mowers. A machine of this type is shown in United StatesLetters Patent No. 247,707, of September 27, 1881.

My object is mainly to simplifyand cheapen in construction and giveincreased strengthand greater durability to certain parts, as will indetail be described in connection with the accompanying drawings, whichshow in part only a suitable machine embodying my improvements.

Figures 1 and 2 are respectively a side elevation and a front elevation,with portions of the machine shown by dotted lines, parts broken awayand other parts in section. Fig. 3 is a side elevation, partly insection, showing portions of a tilting-lever and brace-bar, and themanner in which they connect with each other and with a coupling-arm.Fig. 4 is a view partly in section of a universal joint by which thebrace-bar and coupling-arn1 are connected with the main frame. Fig. 5 isa View in section at a right angle tothe line of section shown by Fig.4.

Driving-wheels A A, a main frame, B, a main-frame arm orcorner-extension, A, together with a tongue, a drivers seat, and allother necessary parts of a suitable machine are of ordinary well-knownconstruction. A coupling-arm, C, is connected at its inner or heel endto the front corner projection of the main frame by a peculiar universalor double joint, instead of being united, as heretofore, by devicesrequiring a number of parts in their con struction, and necessitatingmore or less difficulty in the separation and connection of thecoupling-arm and frame.

As shown in Figs. 4 and 5, the socket D, instead of being made in twoparts detachably connected for insertion and removal of a ball, or, ashas sometimes been the custom, by casting it about the ball, isconstructed as follows: The socket D is formed at its side with an ch10, 1883. (No model.)

elongated opening, (I, and instead of the spherical connecting part orball of the joint apartly circular and partly flattened joint-head, E,is provided. This j oint-head is of a shape such as would be produced bytaking the ordinary ball of the ball-and-socket joint and grinding itdown on opposite sides to produce the flattened faces 6 e, while leavingthe circular or unground portion 6 similar in shape to the corjoints. Byso forming the joint-head it may readily be inserted into the sideopening of the socket, and thus admit of ready connection and separationof the two parts of the joint, while answering all the requirements foror dinary purposes of such joints that the usually employed fullball-and-socket joints do. As willbe seen by inspection of the drawings,the length of the opening in the side of the socket is equal to or veryslightly in excess of the diameter of the circular portion of thejointhead, while the width of this opening is such as to correspond withor slightly exceed the thickness of the joint-headthat is to say, thedistance between its two flattened faces. \Vhen the two parts areconnected and the joint-head turned to the position shown in Figs. 4 and5, it will be perceived that to separate the two parts of the jointwould require a quarterturn. The play thus allowed during the working ofthe joint is ample for the purpose that I especially design it for.

At the outer or free end the coupling-arm has jointed connection with ashoe, F, to which the finger-beam of the cutting apparatus is connectedin well-known way. A roller or ground wheel, F, is mounted indownhangers of the coupling-arms, as heretofore, and this coupling-armalso has two pairs of lugs, f f f f, projecting upwardly and rearwardlytherefrom. A tilting-lever, G, has pivotal connection with the lugs f ofthe coupling-arm, and is provided with a downwardly and rearwardlyprojecting arm, 9, having suitable jointed connection with the lugs f ofthe coupling-arm.

described, with the down-hanger H of the main frame at its rear end, andat its front end is secured with the coupling-arm by the samepivresponding part of the ordinary ball of such A short brace-bar orpush-rod, H, has universal-joint connection, such as hereinbefore IOO otwhich joins the tilting-lever thereto. A rack-arm, I, projects upwardlyand curves forwardly from the brace-bar close to the in ner side of thetilting-lever. A suitable spring-actuated detent or engaging-lug, J, ofthe tilting -lever is caused to interlock with any one of the rack-teethon the brace-bar which may be desired, so as to hold the cuttingapparatus in the desired tilted position. A suitable rocking lever, K,chain 7c, and de tent devices serve to lift the couplingarm inwell-known way for an obvious purpose. From the above description itwill be seen that the coupling-arm and the brace-bar may readily beconnected with and detached from the main frame without the removal ofany bolts and nuts, such as are usually employed to unite the twosections of the socket of the joint; and, further, that theordinarilyemployed separately-formed tilting-levers and connecting-rods,by which they are connected with the coupling-arm or other part of themachine are dispensed with, and the compound or combined tilting-leverand connection with thecoupling-arm is provided, thus greatlysimplifying the construction of this part of the machine.

As in this instance shown, the connection between the arm 9 of thetilting-lever and the coupling-arm is aloose joint-connection, whichfacilitates the ready attachment and separation of the parts, and is asfollows: The arm 9 at and near its lower end is provided on each sidewith two transverse ears, m n, joining with the rear side ribs, 0. Inthis way a partly-open recess or socket, h, is provided 011 each side ofthe arm g, at its end, to receive engaging-lips 19, one on each of thelugs f f, and projecting inwardly therefrom. The lugs f f arestrengthened by being connected at q outside of the roller.

It should be noticed that accidental move 'ment of the brace-barrack-arm away from the side of the lever is prevented by the overlappingportion or embracing-lip Z of the de tent-slide L, the range of movementallowed this slide being such as not to permit it to move far enough torelease the rack.

I claim as of my own invention 1. The joint-socket having the singleelongated side opening to admit of the insertion and removal of thepartly-circular joint-head, which about corresponds in diameter andthick ness, respectively, with the length and width of thesocket-opening, substantially as and for the purpose hereinbefore setforth.

2. The joint-head, flattened or cut away, and having the circularportion to adapt it to work in the socket, the said circular portionabout corresponding with the internal diameter of the socket,substantially as and for the purpose hereinbefore set forth.

3. The two-part joint consisting ofthe combination of the joint-sockethaving an elongated side opening and a partly-circular jointhea'dinserted in and removable from the socket by way of its opening, withthe length of which openingthc joint-head about corresponds in diameter,substantially as and for the purpose hereinbefore set forth.

4. The coupling-arm having the joint-head. flattened or cut away andpartly circular,-its said circular portion about corresponding indiameter with the internal diameter of the joint-socket, substantiallyas and for the purpose hereinbeforc set forth.
